To all whom it may conceui:

Be it known that I, EMIL Austria-Hungary, residing at the city of -Winnipeg, in the Province of Manitoba, Canada, have 1nvented a new and useful Gompositionof Matter to be Used for the Manufacture of Artificial Stone, of which the following is My invention consists of the following ingredients, in the proportions substantially as stated, and prepared as described:

These ingredients are thoroughly mixed together, either mechanically or by manual means. 1 next make a solution of magnesium chlorid by adding thereto approximately to per cent. of Water, or such amount as will make therewith a saturated solution, the solution being allowed to stand at least two days before using. T0 100 pounds of the dry mixture I next add approximately 60 pounds of the magnesium chlorid solution, thoroughly mixing until the mass is in an asily workable plastic be placed in molds, freely following the designs thereof.

As my composition of matter may be made to imitate marble very closely, when a smooth face is required, the material should be cast upon a mirror like surface. Owing to the fact, that my composition after being mixed, first cools and then heats, reaching its maximum heat in about Ghours and becoming cool and solid in about 2% hours, the material upon which it is cast is a matter of importance. Anything of a brittle nature will not do, and if iron be used, owing to the afiinity of the composition for that material, it is necessary that an affinity resisting material be interposed between the metal and the composition. 1

have found nickel plate a Very preferableand magnesium OXiCl will combine to form a stone like substance, it is also known that the substance so formed is subject to rapid deterioration through its-ready absorption of carbon, and atmospheric influences, I therefore overcome these defects and secure permanency by the addition of barium sulfate and lithopone.

The composition may be colored as required, by the addition of pigments, but these should preferably be of.exid origin to secure permanency.

What I claim is 1. llhe herein described composition of mattencompounded in the manner, and in the quantities substantially as described, opnsisting ofmagnesium oxid, and magnesium ohlorid, lithopone, barium sulfate and water, the barium sulfate forming the filler, and the magnesium oxid and magnesium chlorid forming an oxychlorid adapted to combine with and bind the barium to form a hard stone like substance, the lithopone entering into the composition, and giving thereto a smooth marble like surface and preventing the decomposition or sweating of said oxychlorid.

2. The herein described composition of matter, in the quantities substantiallyas follows, magnesium oxid forty five pounds, barium sulfate fifty pounds, lithopone five pounds, and solution of magnesium clilorid sixty pounds, the zinc contained in the lithopone forming with the magnesium oxid and magnesium chlorid a double oxychlorid, substantially secure from deterioration and adapted to bind and combine with the barium sulfate to form a hard, fine grained, smooth marble like substance. 4
